Definitions

  • This invention relates to an improved so-called earless stepless clamp structure which is characterized by greater ease of installation as well as by a greater holding reliability in the tightened clamp.
  • So-called low profile or earless and stepless clamp structures are known from US-A-4,492,004 which first disclosed a clamp structure of this type.
  • US-A-4,712,278 discloses a modified earless stepless clamp structure which sought to avoid the problem for the requirement of special tools.
  • US-A-4,987,651 provides special sections with concavely shaped lateral band portions to overcome the lack of elastic stretchability in the longitudinal direction on the part of the normally used clamping band materials.
  • DE-C-39 30 716 discloses an earless clamp which has the features included in the first part of claim 1.
  • the lifting up of the free end of the outer band portion has been surprisingly minimized in an extraordinarily simple manner by a reinforcement at least partially surrounding the tunnel-shaped embossment member nearest the free end of the outer band portion which is used to tighten the clamp structure by applying a tightening tool at its tool-engaging surface.
  • clamp structure generally designated by reference numeral 10 includes a clamping band 11 made from conventional clamping band material, such as stainless steel or galvanized steel whose inner band portion 11a and outer band portion 11b are intended to overlap in the preassembled and installed positions ( Figures 3 and 5).
  • clamping band 11 made from conventional clamping band material, such as stainless steel or galvanized steel whose inner band portion 11a and outer band portion 11b are intended to overlap in the preassembled and installed positions ( Figures 3 and 5).
  • the free end of the outer band portions 11b may be provided with bevelled edges 13, for example, at an angle of 45° --as is also the case at the free end of the inner band portion 11a-- and is adjoined in the direction away from the free end by a first tunnel-shaped cold-deformed embossment member 14 of approximately semi-circular shape in transverse cross section which is obtained by deep-drawing after two transverse cuts to form the abutment surfaces 14' and 14".
  • a third tunnel-shaped cold-deformed embossment member 19 also obtained by deep-drawing after two transverse cuts to form the abutment surfaces 19' and 19".
  • an improved hook-like support member generally designated by reference numeral 20 which also performs a guide function and serves to retain the clamp structure in its completely tightened condition, the details of which will be described more fully hereinafter.
  • a fourth tunnel-shaped cold-deformed embossment member 18 obtained by deep-drawing after two transverse cuts to form abutment surfaces 18' and 18".
  • the latter is provided with a tongue-like extension 30 adapted to extend through an aperture formed in the outer band portion 11b whereby the aperture commences within the area of two step-like portions 32a and 32b as more fully disclosed in my prior U.S. Patents 4,299,012 and 4,315,348.
  • two longitudinal cuts 33a and 33b are made in the clamping band to obtain a pressed-out channel 33 whereby the two step-like portions 32a and 32b in the outer band portion 11b in which the aperture is located, have a height substantially equal to the thickness of the clamping band so that the remaining lateral band portions 35a and 35b come to lie with their inner clamping surfaces at the radial distance of the inner clamping surface of the clamp structure.
  • the tongue-like extension 30 which is thereby able to extend through the aperture formed in the step-like portions 32a and 32b, can then slide longitudinally in the channel-shaped recess 33 during tightening of the clamp.
  • the tongue-like extension 30 is thereby guided by the inner surface of the outer band portion 11b until extending through the aperture within the step-like portions 32a and 32b as more fully disclosed in my prior U.S. Patent 4,299,012.
  • the stepless feature can also be attained as disclosed in my prior U.S. Patent 4,315,348 in which the part forming the cover of the channel-shaped recess 33 is omitted by simply cutting a longitudinal slot out of the outer band portion which commences in the step-like portions 32a and 32b and extends a predetermined distance in the outer band portion away from the free end thereof.
  • the pressed-out channel-shaped recess 33 thereby terminates in a second step-like portion 34.
  • the reinforcement generally designated by reference numeral 25 which is located between the tunnel-shaped embossment member 14 and the free end of the outer band portion 11b close to the latter, thereby at least partially surrounds the first tunnel-shaped embossment member 14 in a curvilinear manner as shown in Figures 1, 4 and 6.
  • the reinforcement 25 at least partially surrounds the first tunnel-shaped embossment member 14 by a greater amount than in Figure 1 and for that purpose includes a transversely extending, substantially rectilinear main portion 27 ( Figure 7) and two longitudinally extending lateral portions 28a and 28b which are joined to the transversely extending main portion 27 by way of rounded-off portions 29a and 29b each preferably forming a fourth of a circle.
  • the hook-like member generally designated by reference numeral 20 and illustrated in greater detail on an enlarged scale in Figures 10 through 12, is formed by a curvilinear cut 23 ' extending from point x to point y as shown in Figure 12, i.e., at the intersections of the part-circular cut 23' with the straight lateral connecting areas 24a' and 24b' of the lateral portions 24a and 24b of the hook-like member 20 with the remaining lateral band portions 11' and 11".
  • the hook-like member 20 is then cold-deformed by deep-drawing to provide a substantially rectilinear ramp-like rear surface 22 adjoined at the upper end by a flat top portion 23 forming a nose-like projection extending in the longitudinal direction of the clamping band away from the free end of the tongue-like extension 30.
  • the hook-like member 20 is thereby so formed by deep-drawing that the ramp-like surface 22 decreases in width from its connection with the clamping band toward the flat top portion 23 while its lateral portions 24a and 24b also taper as seen in Figure 12.
  • the flat top portion 23 has an approximately semi-circular configuration at its edge 23" ( Figure 12) where the flat top portion 23 is connected with the lateral portions 24a and 24b and with the ramp-like surface 22 so that the inclined edges 24', which can also perform a guide function in addition to the support function, are able to abut at the edge formed by the transverse cut for the first tunnel-shaped embossment member 14 nearer the free end of outer band portion 11b, i.e. at the edge in the clamping band underneath the abutment surface 14'.
  • This particular shape of the hook-like member 20 has proved to be extraordinarily user-friendly to install the clamp owing to the flat top portion which at the same time greatly strengthens the hook-like member against collapse or buckling at the top end of the inclined surfaces as compared to similar prior art hook-like members without the flat top portion, thereby assuring improved holding abilities with respect to circumferentially directed forces so that a single such hook-like member may even suffice.
  • the clamp is placed about the object to be fastened with the small projection 16 engaging in the tunnel-shaped embossment 19 to provide preassembly.
  • the free end of the outer band portion 11b will slide up over the substantially rectilinear inclined ramp-like surface 22 and over the flat top portion 23 of the hook-like member 20 until, in the completely tightened condition, the flat nose-like projection is able to snap-in automatically over the edge in the clamping band underneath the abutment surface 14' of the first tunnel-shaped embossment member 14 to rest on the surface of that outer band end portion indicated in Figures 8 and 9 by reference numeral 11b'.
  • the clamp structure is placed about the object to be fastened and is held in preassembled condition by engagement of the small projection 16 in the third tunnel-shaped embossment member 19. All that is then necessary to tighten the clamp structure is to apply a tightening tool at the abutment surface 14" of the first tunnel-shaped embossment member 14 and at the abutment surface 18' of the fourth tunnel-shaped embossment member 18 so that, after the free end part of the outer band end portion 11b has passed over the surface 22 and the flat top portion 23 of the hook-like member 20, the clamp is automatically installed when the flat hook-shaped top portion 23 of the hook-like member 20 snaps-in over the edge formed by the cut forming the abutment surface 14" at which point the clamp is in the fully engaged position.
  • FIGS. 13 and 14 illustrate the use of one or more undulations generally designated by reference numeral 40 and/or one or more sections 41 consisting of lateral band portions 42 of concave shape and forming therebetween a window 43 resembling an hourglass shape.
  • the undulations 40 which may be of any height and configuration are thereby located in this embodiment within the areas of minimum mutual spacing of the lateral band portions 42.
  • the undulations 40 may also be located elsewhere and may be used without the sections 41, i.e., one or more undulations 40 within the area of the remaining lateral band portions on both sides of the slot-like opening 15 or, in the alternative, only sections 42 may be provided as also any other known section assuring the elastic stretchability.
  • the sections 41 may also be formed with rectilinear outer sides continuing the normal width of the band portion and only cutting out the hourglass-shaped windows.
  • Figures 15 through 24 illustrate a modified embodiment of an earless stepless clamp structure provided with an auxiliary spring generally designated by reference numeral 150 (Figure 19) to provide a desired spring path for tolerance compensation. Similar parts in the embodiment of Figures 15 through 24 corresponding to those of the embodiment of Figures 1 through 12 are designated by corresponding reference numerals of the 100 series and therefore will not be described again in detail.
  • the clamp structure of this embodiment includes a separate connecting member generally designated by reference numeral 200 in which those parts functionally similar to those of the embodiment of Figures 1 through 12 are designated by corresponding reference numerals of the 200 series.
  • the clamp structure of the embodiment of Figures 15 through 24 is again provided with a reinforcement generally designated by reference numeral 125 which is located near the free end of the outer band portion 111b and which may be similar to that illustrated in Figure 1 or preferably similar to that illustrated in Figures 7-9.
  • the separate connecting member 200 includes a support hook member 220 ( Figure 17) similar in construction and operation to the support hook member 20 of the first embodiment.
  • the auxiliary spring generally designated by reference numeral 150 which connects the separate connecting member 200 with the clamping band 111 just ahead of the beginning of overlap, includes a convexly shaped outer portion 151 followed by convexly shaped lateral portions 152a and 152b having smaller radii of curvature than the convexly shaped outer portion 151 and terminating in end portions 153a and 153b which are directed toward one another and are provided at their end faces centrally thereof with projection-like engaging members 254a and 254b, adapted to engage in tunnel-shaped embossment member 261 of the connecting member 200 and in tunnel-shaped embossment member 162 provided in the band portion 111.
  • the inner band portion 111a is provided with another tunnel-shaped embossment member 163 which is adapted to engage in elongated slot-like aperture 260 in the connecting member 200 to form a limiting means preventing overstressing of the auxiliary spring 150.
  • Figure 22 illustrates the details of the two similar tunnel-shaped embossment members 261 and 161 ( Figures 17, 18 and Figures 15, 16).
  • Figure 23 illustrates the details of the two similar tunnel-shaped embossment members 218 and 219 ( Figures 17 and 18) which are similar to the two tunnel-shaped embossment members 18 and 19 of the first embodiment ( Figures 1 and 2).
  • Figure 24 illustrates the details of the two tunnel-shaped embossments 117 and 163 ( Figures 15 and 16) which are similar to the tunnel-shaped embossment member 17 ( Figures 1 and 2).
  • the operation of the embodiment of Figures 15 through 24 is similar to the embodiment of Figures 1 through 12.
  • the embodiment of Figures 15 through 24 may also be provided with some means, as described hereinabove, or as known in the prior art for imparting to the clamping band and/or connecting member an elastic stretchability in the longitudinal direction of the clamping band.
  • the overtorquing feature as well as the particular construction of the tunnel-shaped members and their tool-engaging arrangements as disclosed in my prior U.S. Patent 5, 191, 684 may also be incorporated into the various embodiments of the clamp structures as disclosed herein.
